What is WAAS?
A. WAAS stands for the “Wide Area Augmentation System”. WAAS is an FAA-funded project designed to improve the overall accuracy and integrity of GPS signals for flying in instrument meteorological conditions, primarily during the approach and landing phases of flight. It is a space-based system that broadcasts integrity information and correction data as determined by ground reference stations. At this time, the system is still in the development stage. The goal is to provide reliable signals with an accuracy of seven meters (21-22 ft), both horizontally and vertically, 95+% of the time. Current tests show the actual accuracy to be on the order of 2-3 meters. See http://gps.faa.gov/Programs/WAAS/waas.htm for more information. For those GPS units that are WAAS enabled, a second antenna is not necessary to receive the signal. • Q. Is the iQue waterproof? A. Unlike most GPS units that Garmin has introduced, the iQue 3600 does not have a waterproof rating. The iQue is not recommended for us
The Wide Area Augmentation System (WAAS) is a GPS-based navigation and landing system that provides precision guidance to aircraft at thousands of airports and airstrips where there is currently no precision landing capability. Systems such as WAAS are known as satellite-based augmentation systems (SBAS). WAAS is designed to improve the accuracy and ensure the integrity of information coming from GPS satellites. The FAA is using WAAS to provide a Lateral Navigation/Vertical Navigation (LNAV/VNAV) capability with commissioning in 2003. Concurrently, the FAA will evaluate the approach to achieve Global Navigation Satellite System (GNSS) Landing System (GLS) capability in later years. WAAS testing in September 2002 confirmed accuracy performance of 1 2 meters horizontal and 2 3 meters vertical throughout the majority of the continental U.S. and portions of Alaska. WAAS stands for Wide Area Augmentation System. WAAS is a system of satellites and ground stations that provide GPS signal corr
